How many of us are there? Owners of Dodge based RV's?

Hello All "Vintage Class C Dodgers". I just aquired a 79 22' Brougham on a 78 Dodge Sportsman with a V8 318 motor. I also am having to do restoration work on mine. It has 38,234 original miles.
This is my Brougham Class C. I want to do a full restore eventually. This year it also qualifies for a vintage tag. I still have all original documentation/schematics for Dodge, Duo-therm AC, Kohler Generator, furnace, Etc that came with it. I paid $1000 for mine.
My 78 Brougham

Any Advice on used/surplus parts??
